A Geometric View for Understanding Concept Learning and Neuron Interpretation in Sparse Autoencoders
arXiv:2606.07007v1 Announce Type: new Abstract: We propose a unified mathematical framework for a geometric understanding of concept learning and neuron interpretation in sparse autoencoders (SAEs). While SAEs improve interpretability of neural networks by learning sparse feature representations, a principled definition of ''concept'' and ''learning'' remains unclear. We formalize concepts as sets of data points and cast concept learning as a set-alignment problem between human-defined and model-induced concepts. This formulation distinguishes three increasingly strong notions of learning -- d
The paper presents a unified mathematical framework at a time when 'interpretability' and 'explainability' are critical hurdles for AI adoption and safety, particularly for sparse autoencoders (SAEs).
Improved understanding of how neural networks learn concepts and interpret neurons directly contributes to more robust, reliable, and trustworthy AI systems, which is crucial for high-stakes applications.
This formalization provides a structured approach to defining 'concept' and 'learning' in neural networks, moving beyond heuristic interpretations towards a principled geometric understanding.
